A lot of digital art has spand many areas of life. Some very serious, taking serious big data to transpose into graphic visual works. For example, treating conceptual reflexion of world data, ie. how much people eat oranges in developed countries compared to developing countries; how much porn sites visited, what kind of favorite kinks; the amount of internet use globally as data displayed in network trajectory frequencies... stock market data linked to the rise of a penis, etc etc.
The kind of digital art that I personally really appreciate is something a little silly, something for everybody.
Fun, entertaining that everyone young and old could relate to.
For example: the How Old are you? instant online game. Just upload a photo and the software analyse how old you might be. Its fun, non aggressive, everybody has a face, everybody gets old, and everybody likes to be in disguise everynow and then. Such a generous fun thing for people to take account of their own appearance, their inner self, their wannabe self.
So, a very nice application. Try it, its free.
